+由于新下载库仍然没有完成，但下载功能已经可用，so 移除之前使用的第三方下载库，暂时把新下载库的下载模块直接加入本程序，若出现下载问题欢迎反馈！
+
 ### 新增
 
-- 新增歌曲缓冲定时器，尝试用于解决网络正常但是歌曲缓冲过久的问题
-- 新增下载管理的任务状态分类
-- 添加**杀毒软件提示有病毒或恶意行为**的说明，可到**常见问题**拉到最后查看（常见问题可在开源地址找到）
+- 新增下载功能对代理设置的支持，现在若在软件设置了代理服务器，下载功能也将会走代理网络了
 
 ### 优化
 
-- 优化更新弹窗机制及其内容描述，对于可以自动更新的版本，现在可以看到软件的下载进度了
+- 新下载模块将对恢复下载的任务进行字节校验，用于解决下载进度超过100%后仍然下载的问题
+- 注意：目前仍然无法暂停处于**链接获取**状态中的任务
+
+### 修复
+
+- 修复下载列表歌曲状态分类列表操作Bug
+- 修复歌曲封面下载失败时仍然执行嵌入封面操作导致报错的问题
+- 跳过重复添加**相同歌曲名与扩展名的歌曲**，例如你之前下载了A歌曲的128k音质，现在想要下载它的320k音质，但由于两者都是MP3格式，会因为重名导致之前的128k音质被覆盖但列表中仍然显示两种音质的问题（但实际上都是指向后面的320k音质）
